When at home, my mobile phone signal is poor (3 or 2G) so I have WiFi calling switched on.
If the phone switches to WiFi all is well but if it thinks the signal is strong enough, no calls can get in or out.
My solution is to go into airplane mode which forces it onto WiFi. Having to do that everytime I come in and go out is not ideal. It used to work fine and I have not changed the phone (Samsung A35 5G)
I have set the phone to reboot every morning.
Any suggestions?
